# CJC-1295 Peptide: Benefits, Dosage, Risks, and Where to Buy

[Disclaimer: This article is for informational and educational purposes only. CJC-1295 is not FDA-approved for human consumption and is currently only available for research purposes. The information provided does not constitute medical advice.]

CJC-1295 is closely connected to human growth hormone (HGH or GH), a key hormone in your body that controls growth and development.

Your body uses GH for much more than just getting taller—it helps build muscle protein, burns fat more efficiently, boosts energy levels, and makes workouts more productive.

These benefits make GH optimization important for everyone, regardless of your age.

Many biohackers consider CJC-1295 peptide one of the safest and most effective compounds for boosting your natural GH production. This guide will show you everything you need to know about CJC-1295 and its proper use.

## What is CJC-1295? Does CJC-1295 Work?

CJC-1295 is a modified version of something your body already produces called growth hormone-releasing hormone (GHRH).

It was originally developed by ConjuChem Technologies, a Canadian biotech company, which is where it gets its name.

You might hear people refer to it as “CJC-1295 DAC” or “DAC: GRF” – don’t let these technical terms confuse you. The “DAC” part (drug affinity complex) is just a special modification that helps the peptide last longer in your body.

While researchers are still conducting human clinical trials to fully understand its benefits, CJC-1295 has caught the attention of the athletic and medical communities, which often seek the best peptides for athletic performance.

They’re interested in CJC-1295 because early research suggests it could improve body composition, potentially helping people build muscle and lose fat more effectively.

It offers similar benefits to traditional growth hormone treatments but with fewer side effects.

### Sermorelin vs. CJC-1295

Sermorelin, also known as GHRH 1-29, is another GHRH analog that works similarly to CJC-1295.

However, there are some key differences:

- Half-life: Sermorelin lasts only 11–12 minutes, while CJC-1295, due to the DAC technology, has a half-life of around 5.8 – 8.1 days.
- Dosing Frequency: Sermorelin must be taken daily, whereas CJC-1295 only requires 1-2 doses per week.
- Strength: With its longer half-life, CJC-1295 exhibits greater strength and potency than sermorelin.
- Side Effects: CJC-1295 tends to produce fewer side effects since it mimics natural GHRH more closely.

#### Can You Take CJC-1295 and Sermorelin Together?

While technically possible, no research supports additional benefits from combining these peptides.

Since CJC-1295 is essentially an enhanced version of Sermorelin, using them together would likely be redundant.

### Tesamorelin vs. CJC-1295

Tesamorelin is another growth hormone-releasing peptide that is typically used to reduce excess abdominal fat in HIV patients.

Here’s how the two compare:

- Tesamorelin has a shorter half-life of ~26–38 minutes.
- CJC-1295 produces more sustained hormone elevation.
- Tesamorelin use is associated with elevated glucose and HbA1c levels, which isn’t seen with CJC-1295.
- Tesamorelin (Egrifta) is FDA-approved for specific medical use.
- CJC-1295 is currently only available for research purposes.

### BPC-157 vs. CJC-1295

BPC-157 is a different type of peptide that consists of 15 amino acids.

BPC-157 has local effects, such as healing leaky gut, speeding injury recovery, and protecting against damage from NSAIDs.

These peptides serve different purposes:

- BPC-157 primarily promotes healing and tissue repair
- CJC-1295 focuses on growth hormone release and associated benefits

They can potentially be used together as their mechanisms don’t conflict.

## CJC-1295 DAC vs. No DAC

Here’s how the two versions compare:

Aspect | CJC 1295 DAC | CJC 1295 No DAC
Purpose | Increases GH/IGF-1 levels for an extended period | Increases GH/IGF-1 levels briefly
Duration of Action | Effects last 6-8 days after injection, with IGF-1 elevated for up to 28 days | Effects peak within 1-2 hours and decline rapidly
Frequency of Injections | 1-2 times weekly | Daily
Formulation | CJC-1295 + Drug Affinity Complex (DAC) | CJC-1295 peptide only (No DAC modification)
Half-Life | 5.8-8.1 days | ~30 minutes

## What Does CJC-1295 Do?

A study by Teichman and his team in 2006 showed just what a single CJC-1295 injection can do:

- It can boost your growth hormone (GH) levels by 2 to 10 times their average amount, lasting almost a week. Higher GH levels mean your body becomes more efficient at building muscle and burning fat.
- The injection also increases your IGF-1 (Insulin-like Growth Factor 1) levels by 1.5 to 3 times for up to 11 days. IGF-1 is your body’s natural anabolic steroid – a hormone that helps build and preserve muscle tissue.
- When you take multiple doses, your IGF-1 levels can stay elevated for up to 28 days!

## CJC-1295 Benefits

Based on the activity we just mentioned and some small-scale studies and animal research, here are the benefits CJC-1295 provides:

### Build & Maintain Muscle Mass More Effectively

CJC-1295’s ability to boost both growth hormone and IGF-1 levels makes it perfect for muscle growth.

The peptide helps stimulate protein synthesis (building new muscle) and supports overall muscle mass development.

You’ll find CJC-1295 in many peptides for muscle growth listicles.

### Get Better Sleep Quality

If you’re struggling with sleep, CJC-1295 might help you rest better.

Since it’s a synthetic version of GHRH (growth hormone-releasing hormone), which plays a crucial role in sleep quality, researchers are excited about its potential.

A thorough study by Fehm and colleagues investigated this connection.

They conducted a double-blind study (meaning neither researchers nor participants knew who received what) with 23 healthy men — 12 young and 11 older subjects.

Each participant received 300 micrograms of GHRH or a placebo 30 minutes before bedtime.

The results for the GHRH group were:

- Lower cortisol levels at the beginning of sleep (cortisol is your stress hormone)
- Better control of growth hormone levels during early sleep
- Increased REM sleep (crucial for mental recovery)
- More slow-wave sleep (SWS) in the latter half of the night (vital for physical recovery)

Quality sleep helps your muscles recover from injury, and growth hormones have been shown to improve non-REM sleep after periods of sleep deprivation.

### Shed Stubborn Body Fat

Studies have found that prolactin (a hormone in your body) can increase visceral fat — the stubborn fat around your organs.

CJC-1295 has been shown to help normalize prolactin levels, as examined in studies with GHRH knockout mice. This normalization could lead to better fat burning in your body.

### Boost Your Brain Power & Performance

Growth hormones don’t just affect your muscles and fat – they play a role in how well your brain works, particularly in learning and memory.

In an animal study, researchers found that mice with enhanced growth hormone activity performed notably better on learning tests than regular mice.

Note: Though these early results are promising, we need more research to understand how CJC-1295 affects humans entirely. Most of our current knowledge comes from animal studies, as this peptide is still in the research phase and hasn’t been extensively tested in humans for these specific benefits.

## How CJC-1295 Peptide Works

Here’s what happens when you take/inject CJC-1295 peptide:

1. CJC-1295 enters your bloodstream and binds to albumin (a blood protein), which helps it stay active for 8-10 days.
2. It then travels to your pituitary gland and binds to receptors on special cells called somatotropes.
3. When bound to these receptors, it signals the cells to make more growth hormones.
4. The cells also release their existing growth hormone into your blood.
5. This leads to higher levels of both growth hormone and IGF-1 in your body.
6. Unlike synthetic growth hormone injections, CJC-1295 maintains your body’s natural pulsing pattern of hormone release.

In simple terms, CJC-1295 tells your body to release the growth hormone it has stored and make more of it.

But GHRH (and therefore CJC-1295) doesn’t just affect your pituitary gland. Its effects reach throughout your body, influencing how cells grow and multiply in various tissues.

This wide-reaching impact is why cancer researchers are particularly interested in understanding how it works.

To give you an idea of how powerful CJC-1295 is, a 2005 study with male Sprague Dawley rats showed that it could stimulate a “4-fold increase” in growth hormone (GH) levels.

When researchers combined CJC-1295 with hGRF1–29 amide and CJC-1288, they saw the biggest spike in blood growth hormone levels ever recorded in the rats in their two-hour testing window.

This means CJC-1295 not only worked well on its own but achieved record-breaking results when combined with other peptides!

## CJC-1295 Dosage and Timing

Due to its extended half-life, CJC-1295 only needs to be injected 1-3 times per week for sustainable results.

Typical dosing protocols involve injecting 1-2 mg (1000-2000 mcg) per injection. Timing the injection before bed works well since natural GH release peaks during early sleep.

### How Much CJC-1295 Should I Take?

Most clinical trials, like Teichman and his team’s research, have used body-weight-based doses of 30-60 mcg/kg injected once weekly.

If you weigh 80 kg (176 lbs), that equals 2,400-4,800 mcg (2.4-4.8 mg) per injection.

Anecdotal evidence suggests splitting this dosage into smaller injections 2-3x weekly. It may help sustain consistent GH levels.

#### CJC-1295 Dosage for Weight Loss

No studies directly claim that CJC-1295 can help you lose weight without any external force.

However, one study published in the Growth Hormone & IGF Research journal shows that GH administration notably accelerates abdominal/visceral fat reduction.

Here is the dosage you can follow:

- Starting dose: 1000mcg (1mg) weekly (DAC version)
- Can be increased to 2000mcg based on the response
- Best taken before bed on an empty stomach

Time injections before cardio workouts to further optimize your body composition.

#### CJC-1295 Dosage for Bodybuilding

Due to its ability to elevate IGF-1 (which stimulates muscle protein synthesis) and induce hyperplasia, a weekly CJC-1295 dosage of 1-2 mg (1000-2000 mcg) might increase muscle mass.

This dosage can be timed around your workout. Specifically, you can take one of your daily injections shortly after exercising when your body is primed for muscle growth and recovery.

Anti-aging clinics also frequently prescribe CJC-1295 alongside other peptides like sermorelin or ipamorelin for better outcomes.

### Where to Inject CJC-1295

CJC-1295 is injected subcutaneously, meaning into fat tissue instead of muscle.

Good injection sites with looser skin that avoids veins/nerves include around the navel, love handles, outer thigh, or upper glute.

Ensure to fully inject the solution once the needle is under the skin rather than pulling in/out.

### How Long Does CJC-1295 Take to Work?

If you’re using CJC-1295 DAC, you’ll need some patience.

It typically takes 3-6 months to see an “upregulation”—when your pituitary gland starts producing consistently higher amounts of growth hormone.

Teichman and his colleagues found: after taking multiple doses of CJC-1295 DAC, people maintained elevated IGF-1 levels (a key marker of growth hormone activity) for up to 28 days, even after stopping the peptide.

The No DAC version works differently, but honestly, we have less human research to go on. However, studies on similar peptides (modified versions of GRF(1-29)) give us some clues:

- Initial effects start quickly – within 2 hours of taking it
- Benefits remain consistent with daily use for up to 16 weeks
- No studies have tested these peptides beyond 16 weeks

16 weeks might seem like a long time, but researchers are just being cautious – they simply haven’t tested longer periods yet.

## Peptide Therapy: CJC-1295 and Ipamorelin

The combination of CJC-1295 and Ipamorelin represents one of the most studied peptide therapy protocols.

This combination works synergistically – CJC-1295 maintains sustained growth hormone (GH) levels, while Ipamorelin creates powerful GH pulses by stimulating ghrelin receptors.

### CJC-1295 Ipamorelin Side Effects

Despite the synergy, here are some common side effects to note:

- Injection site reactions (redness, irritation)
- Temporary water retention
- Mild headaches
- Tingling sensations
- Increased hunger

### Ipamorelin CJC-1295 Dosage

Studies mentioned above and anecdotal evidence typically follow these guidelines:

#### How Much CJC-1295 Ipamorelin Should I Take?

Standard dosages:

- CJC-1295: 100mcg per day (No DAC version)
- Ipamorelin: 100-200mcg per day
- Administration: Split into 1-2 daily doses

#### CJC-1295 + Ipamorelin: Bodybuilding Dosage

For body composition:

- CJC-1295: 60mcg/kg
- Ipamorelin: 100mcg/kg
- Administration: Biweekly protocol for sustained effects

The same protocol applies when combining CJC-1295 and Ipamorelin for muscle growth.

### CJC-1295 + Ipamorelin: How Long Does It Take to See Results?

Based on research protocols, results typically develop as follows:

- Initial hormonal changes: 1-2 weeks
- Noticeable composition changes: 4-6 weeks
- Full benefits: 8-12 weeks
- Effects can persist up to 28 days after administration

## CJC-1295 Side Effects and Risks

Since CJC-1295 simply mimics natural GHRH, side effects tend to be mild.

The most common include redness or itching at the injection site and occasional headaches. Rarely, symptoms like fatigue, nausea, or dizziness may surface temporarily.

It doesn’t interfere with other hormone axes, either.

However, it hasn’t been studied in the long term, so theoretical risks like glucose instability, carpal tunnel syndrome, or cancer risk can’t be definitively ruled out.

One critical note for athletes:

CJC-1295 is strictly prohibited by the World Anti-Doping Agency (WADA).

If you’re a competitive athlete subject to drug testing, be aware that anti-doping authorities routinely screen for this peptide, and violations carry severe penalties.

The risk of detection and subsequent sanctions isn’t worth it.

## Is CJC-1295 Safe for Long-Term Use?

No large-scale studies have evaluated CJC-1295 for longer than 16 weeks thus far. However, research on comparable GHRH analogs can infer its safety over extended periods.

For example, sermorelin has been clinically administered for over a decade with excellent safety data.

Since CJC-1295 works via a similar natural mechanism to increase GH levels, experts consider it to be as safe in the long term.

## Frequently Asked Questions (FAQs)

Here are answers to some often-asked questions regarding CJC-1295 treatment:

### How Quickly Will I See Results From CJC-1295?

Blood tests show an increase in GH and IGF-1 within hours after injecting CJC-1295. However, visible anti-aging effects and physique changes happen gradually over subsequent weeks and months.

It may take about 4-8 weeks before noticing substantial improvements to body composition, skin quality, energy levels, etc.

For those exploring peptides to enhance vitality, considering the best peptide for energy can provide insight into complementary options that may boost overall results.

### What Happens When You Stop Taking CJC-1295?

Since CJC-1295 doesn’t supply external GH (it stimulates natural production instead), GH and IGF-1 levels naturally taper back to baseline within about one month after stopping treatment.

Depending on diet, you may regain some body fat, but muscle tissue and anti-aging effects should remain relatively persistent months later owing to lasting gene expression changes.

### Does CJC-1295 Increase Testosterone?

There is no concrete evidence that CJC-1295 directly raises testosterone levels.

However, downstream hormonal balance changes from higher GH & IGF-1 may support secondary boosts in luteinizing hormone, DHEA, and testosterone.

## Conclusion

CJC-1295 seems like a promising option if you’re interested in growth hormone optimization and want benefits for body composition, recovery, and anti-aging.

While research is still ongoing, current evidence suggests it’s generally safe and effective when used responsibly.

As with any peptide, proper dosing, cycling, and medical supervision are non-negotiable for optimal results and safety.
